Application filed June 16, 1907. Serial No. 379,193.

`To all 'whom4 it may concern:

invent ed a new and useful Automatic Alarm-` Valve.

This .alarm valve is designed princi ally for use in factories and large builiings where a supply of water is kept for the pui ose of .extinguishing tires. As is well mown,most large factories, department stores have a large water tank 'or tanks on the roof of the buildincr oi' some other source ot water supply, in w iicli large quantities of water are stored and there are pipes running from them usually on the ceiling of the rooms in which it is desired to prevent fire and these pipes have fusible metal or some similar device so that when a tire is started the heat of the tire will melt the fusible metal in the water pipe and the water will be sprinkled on the goods and in the room where the tire starts. Aty times these fusible plugs or similar device give way7 'and the water will-sometimes run out andspoil a lot of goods before it can be shut. otl'.

The purpose of my invention is to have method of detecting any change in the pressure of water in the pipes running to the various parts of the building.

My invention consists of a device, the several partis constructed and arranged as will be hereinafter more fully described and drawing inwhich the same parts are designated by the saine letters an( manner of reierence throughout the several views.

Fi re 1 represents a main water pipe in a building showing the pressure. of water from the street or other source into the building and this plipe also leadsotf into various parts of te building into other ipes of the same or a smaller size as may e desired. This ivure also shows the ordinary valve with a c apper and iny improved automatic alarm valve attached thereto. It also shows the device for making the circuit and ringing the electric bell, and also the motor alarm gong fastened on the outside of the wall of the building. Fig. 2 shows a detailed view of my invention. Fi 3 shows the clapper of an ordinary va ve with my invention attached thereto.

"lliisfli'pper is designated by the lletter i. f Ot Ycourse as long as the pressure reina'insthe saine on eac i side of the clapper E the cla'pper will remain in its norma shut position shown in thediawing The moment however the of Fig. 1 is decreased to any extent whatsoever, the pressure of water om the right hand side will cause the clapper B to rise to the position shown by the dotted lines in Fig. 1. The clapper B will also rise higher and thus pei-mit a free How of water through the pipe. The dotted line position indicated in Fig. 1 shows it only partly raised.'

l\fly device consists of an acorn shaped inet-al auxiliary valve C attac-hed to the clappei B ofthe large valve. rThis auxiliary acorn shaped metal valve C has a number ot' holes D forequaliziiig the pressure ot water, and inside of the acorn shaped valve C is a loose movable metal ball E, somewhat larger than the bottom opening D This ball E when in its nornialposition and when the pressure is the same on both sides of the valve rests tightly over the valve seat of opening F in the pipe A. In this escape opening F is inserted a connecting pipe G. This escape pipe Gr 'connects with an ordinary piston ll, having a plunger iVhen leads to the tank oi port ions of the building desired to be protected by water becomes less than pressure on of a ii'e or a break in the pipe, the water running in from the street or source of supply raises the clappcr ,B of the valve into the position shown by the dotted lines iu Fia". 1., or hi her according tothe pressure, ant the auxi iary valve C with the ball E inside of it. is forced away from the escape openin in the pipe A and the water runs througi the opening F into the pipe G and Jforces the plunger l of the piston ll upward until it strikes against two contact points J of an electrical connection making' the circuit and ringing the bell K. There is a the pressure in the pipe to the left, which pressure in the pipe on the left hand side eov4 theright 'either by reason 4 Diston (shown in the drawing bv dotted |4 lines), which forces the plunger o the piston back after the alarm has been given. The valve olapper B and the pipe G before mentioned also is constructed to run and operate a rotary gong M on the outside of the building asshown in Fig. 1, or to any other desired place.

While the accompanyin drawing shows one form gf lnydevice an one use of it, I do not wish 4to berestrieted to this, but lay claim broadly to an automatic valve consisting of a metal frame having holes therein and a metal ball slightly larger than the hole in the bottom of the valve. A

Havincr described' my invention, what I claim and desire to secure by Letters Patent of the United States is the following:

1. An automatic alarm valve consisting of a hollow metal body, holes in said body, a

loose metal ball in said body larger than the bottom hole.

2. VAn automatic alarm valve consisting of a hollow metal body, holes in said body, a loose freely moving stopper for one or more of said holes larger than the largest or bottom hole.

3. In combination un automatic alarm valve, olapper of a valve and a hollow metal attachmentr for said clapper, holes in said metal attachment,- and. a metal balll freely moving in said attachment larger than the holes.

In testimony whereof, I have hereunto nftixed my naine to this specification in the 35 presence of two subscribing Witnesses.
